Abstract
A heat-fusion bonding adhesive is prepared by heating a thermoplastic resin to a temperature of no less than the softening temperature of the resin and then dispersing the resin in the softened state in an aqueous medium. Dispersing the thermoplastic resin in the aqueous medium is conducted, for example, by applying a shear force to the aqueous medium by stirring. In this case, stirring of the aqueous medium is preferably conducted till the thermoplastic resin is divided into particles with a weight-average particle size of 0.1-20 &mgr;m.
